Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478392, here are decompositions:
- 41 + 478351 = 478392
- 53 + 478339 = 478392
- 71 + 478321 = 478392
- 139 + 478253 = 478392
- 149 + 478243 = 478392
- 151 + 478241 = 478392
- 179 + 478213 = 478392
- 193 + 478199 = 478392
Showing the first eight; more decompositions exist.
